Welcome to our range of Brushed DC Motor Controllers from Pololu and other brands. These are DC motor drivers with additional intelligence: an on-board microcontroller generates the low-level signals and presents the user with higher-level interfaces and commands.
For example, our dual serial motor controllers allow two DC motors to be controlled by a single serial line, and the master controller simply issues commands only when the speeds of the motors should be changed. Other motor controllers are even more complex, incorporating advanced acceleration commands, current sensing, feedback-based control, and more.
